Morgan-McClure Motorsports will have Todd Bodine driving its No. 4 Chevrolet at Homestead Miami Speedway, taking the place of Ward Burton.
Burton had failed to qualify in the past three and six of the past eight Nextel Cup races.
"Ward has worked hard for us this year, he is a good driver and a friend," team president Tim McClure said.
"Todd has been helpful to us in the past and has agreed to step in and help us benchmark our efforts as we get ready for the 2008 season."
